STK4221V

Ordering number : EN4586A Thick Film Hybrid IC STK4221V 2-Channel 80 W min AF Power Amplifier (Split Power Supply) Features The inclusion of a muting circuit on-chip allows all types of impulse noise to be excluded. Current mirror circuit application reduces distortion to 0.008%. Pin compatible with the STK4201II Series (THD = 0.4%) and the STK4141X Series (THD = 0.02%) Package Dimensions unit: mm 4086A [STK4221V] Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Thermal resistance Junction temperature Operating case temperature Storage temperature Available time for load shorted Symbol VCC max θj-c Tj Tc Tstg tS* VCC = ±45 V, RL = 8 Ω, f = 50 Hz, PO = 80 W Condition Rating ±65 1.4 150 125 –30 to +125 1 Unit V °C/W °C °C °C sec Note: Use a constant voltage power supply as the test power supply unless otherwise specified. * Use the transformer power supply shown on the next page when measuring the available time for load shorted and the output noise voltage.
